This was just a quick shot done this lunch time to check the techniques for the "oil and water" part of this coming Friday Night at the Studio. This image is more or less straight out of the camera. The only post processing involved has been a "levels" adjustment (using exposure and blacks in LR), a boost to the saturation and an increase in clarity, and a slight crop. The image isn't quite as sharp as I would like as my tripod is at the studio and was doing this at home.
How was it done…. well you will just have to come along to the event on Friday to find out! ;-) See: http://www.ians-studio.co.uk/events/event/smokeoilwater/
